Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connector for connecting an electronic device and a cord, and more particularly, to a technique for securing a tensile strength of a cord.

[0002]

2. Description of the Related Art In recent years, the market for portable electronic devices such as portable telephones, PHSs (simplified wireless telephones), and PDAs (portable information terminals) has been rapidly expanding. Furthermore, the number of electronic device terminals (hereinafter, referred to as portable electronic devices) capable of performing data communication through a telephone line by itself or by connecting to a personal computer is increasing.

[0003] A DC code with a connector is generally used when performing data communication or charging using a portable electronic device such as a portable telephone or a PHS.

Hereinafter, a conventional connector will be briefly described with reference to FIG. In FIG. 3, reference numeral 1 denotes a connection connector for connecting a portable electronic device to a DC cord 3 described later through a connector section 6. Reference numeral 2 denotes a bushing portion, which covers the periphery of the DC cord 3 near the connector 1 and has a structure in which a part is inserted into the connector. The portion (contact portion 10) of the bushing portion 2 inserted into the connection connector 1 is in contact with the DC cord 3 side of the connection connector 1, and the bushing portion 2 is partially connected to the connector 1 It is inserted in.
Reference numeral 3 denotes a DC code, which bundles core wires 4 described later into one,
The tube is covered with the tube until it passes through the inside of the bushing portion 2, and is integrally formed with the bushing portion 2 and the corresponding portion.

[0005] Reference numeral 4 denotes a core wire, which supplies electric signals such as current and voltage to a portable electronic device.

Reference numeral 5 denotes a screw hole, which has a structure in which screws are used to fix the upper and lower cases of the connector 1.

In the connection connector having such a configuration,
In order to secure the tensile strength when the DC cord 3 or the bushing part 2 is pulled, it has been dealt with by providing the contact part 10 for bringing the bushing part 2 into contact with the connector 1 as described above.

[0008]

However, in the above-described conventional configuration, although the DC cord 3 and the bushing portion 2 are integrally formed, when the DC cord 3 is pulled by a strong load for some reason, or when only the DC cord 3 is pulled. In some cases, such as when pulled, sufficient tensile strength may not be obtained.

An object of the present invention is to solve such a conventional problem, and an object of the present invention is to provide a connector having excellent tensile strength of a DC cord and a bushing portion.

[0010]

In order to achieve the above object, the present invention provides a connector for connecting to an electronic device, a cord covered with a bundle of core wires, and a bushing covering the cord. In a connection connector formed by fitting or screwing a case and a lower case, a holding portion that has entered the inside of the connection connector of the bushing portion is provided to abut and hold the cord side of the connection connector and a holding portion. The holding portion, which is held between the protrusion and the screw hole and enters the inside of the connector of the bushing portion, is configured to be held in contact with the protrusion or the screw hole.

[0011] Thus, it is possible to provide a connector with excellent tensile strength of the cord and the bushing portion.

Further, a knot is formed at a portion where the cord enters the inside of the connector, and the bushing portion and the cord are integrally formed so that the knot enters the inside of the bushing portion, thereby further increasing the tensile strength. It is possible to provide an excellent connector.

[0013]

Embodiments of the present invention will be described below in detail with reference to the drawings. 1 and 2 are cross-sectional views showing the inside of a connection connector according to an embodiment of the present invention.

In FIG. 1, reference numeral 1 denotes a connection connector;
The portable electronic device is connected to a DC code 3 described later. Reference numeral 2 denotes a bushing portion, which covers the periphery of the DC cord 3 near the connector 1 and has a structure in which a part is inserted into the connector. The portion of the bushing portion 2 inserted into the connector 1 is divided into a holding portion 7 and a holding portion 8. Further, the bushing part 2 is inserted into the connection connector 1 at a part thereof which is thinned.

Reference numeral 3 denotes a DC cord, which bundles a core wire 4 to be described later into a single piece, and is covered with a tube until it passes through the inside of the bushing part 2, and is integrally formed with the bushing part 2 and a corresponding portion thereof. 4 is a core wire,
It supplies electric signals such as current and voltage to portable electronic devices. Reference numeral 5 denotes a screw hole, which has a structure in which a screw is used to fix the upper and lower cases of the connector 1. Reference numeral 6 denotes a connector, which is inserted into a corresponding portion of the portable electronic device.

In the connector having such a configuration,
The structure of the present invention in which the tensile strength is enhanced will be specifically described.

The holding portion 7 is in contact with the DC cord 3 side of the connector 1 and is held between the DC cord 3 of the connector 1 and the screw hole 5. The holding portion 8 is configured to be held in contact with the screw hole 5, and is formed in a trapezoidal shape as shown in FIG. At this time, the screw hole 5 also has a shape corresponding to the shape of the holding portion 8.

Thus, the DC code 3 can be set by the user.
When the bushing portion 2 is pulled or the like, the tensile strength can be greatly improved as compared with the conventional case where only the contact portion 10 secures the tensile strength.

It is to be noted that if the connection connector does not have a structure in which the upper case and the lower case are screwed using the screw hole 5, that is, a connection connector of a so-called fitting type, the screw hole 5 is a member that does not exist. However, in this case, by providing the protrusions at positions corresponding to the screw holes 5 in the same shape, the same configuration and effect can be obtained.

Next, another embodiment will be described with reference to FIG. Although there are some differences in shapes from 1 to 8, they have the same functions as those in FIG. In the figure, the connector 1 of the DC cord 3
It is an internal part, and in contact with the holding part 8,
By knotting pieces, they make knots.

Thus, even when only the DC cord 3 is pulled by some load, the bushing unit 2 can be used.
Since the tensile strength is secured by the portion held by integral molding with the knot and the knot, the tensile strength can be further improved.

The knot shown in FIG.
It is even better to put it inside and integrally mold it. Thus, even when only the DC cord 3 is pulled by some load, not only the part integrally formed with the bushing part 2 and the knot, but also the holding part 7 and the holding part 8 contribute to securing the tensile strength. Therefore, the tensile strength can be further improved.

The present invention relates to a connector. In the description of the present embodiment, the target device is a portable electronic device. However, the present invention is not limited to this. It goes without saying that it is used for Similarly, it goes without saying that the code is not limited to the DC code.

[0024]

As is clear from the description of the above embodiment, according to the present invention, there is provided a connection connector capable of obtaining a sufficient tensile strength even when a DC cord or a bushing portion is pulled by some load. it can.
